Radio Receivers
In a ratio detector

the linearity is worse than in phase discriminator
the output is twice that obtainable from a similar phase discriminator
stabilization against signal strength variations is provided
the circuit is the same as in a discriminator, except that the diodes are reversed

Radio Receivers
Indicate the false statement. Noting that no carrier is transmitter with J3E, we see that

The transmission is not compatible with A3E
Production of AGC is a rather complicated process
The receiver cannot use a phase comparator for AFC
Adjacent-channel rejection is more difficult

Radio Receivers
In a radio receiver with simple AGC

The faster the AGC time constant the more accurate the output
An increase in signal strength produces more AGC
The highest AGC voltage is produced
The audio stage gain is normally controlled by the AGC
